VMware Support is now aware of this issue and has an internal KB article about it. If you avoid upgrading to Feature Pack 2 or avoid applying the Microsoft Lync Security Update, you should be able to avoid the problem.

VMware support said we should see Feature Pack 3 for Horizon View in Q4. Of course, I was told that a few months ago and we are just entering Q4. But they said FP3 was running in their lab and did not have problems with Microsoft Lync 2013 the way Feature Pack 2 has.
